Flat, Beveled, Chiseled & Stepped Brush Trim Shapes

Trim Shapes of the brush face are available in various profiles to accommodate particular applications (examples shown). 

Flat Beveled

The flat trim shape is where the brush filament is set in an even length, resulting in a flat brushing surface. This is the most common shape and is considered the standard profile. This is the shape that will typically be used, unless the application calls for a special shape.

The beveled trim profile, also known as the "angled" shape, is where the brush filament is arranged with a consistent degree of slope to create an angled brushing surface. The purpose of this shape is to reduce brush resistance and conform to certain surfaces.

Chiseled Stepped

The chiseled, or "converging" profile, is a brush shape that resembles a dome with the filament converging towards the center. This shape creates a greater concentration of filament for more focused or aggressive brushing action.

The stepped, or simply "step" profile is a brush shape with the filament arranged with differing heights at intervals, resulting a shape resembling a staircase. This shape is used to create uniform contact with uneven or irregular surfaces, and there are many variations possible.

Concave Convex

The concave brush profile is a result of the filament being arranged to create a curved brushing surface with the outer edges making contact first. This shape is used to conform to certain unique surfaces.

The convex brush profile is simply the reverse of the concave profile, with the filament creating a curved brushing surface that results in the inside filament making contact first. This shape is used to conform to certain unique surfaces.
